Thread: Telematics.net

would you be up for making animation clips in between screens...
ie:
1.click on dvd button (dvd button has word DVD over a DVDdisk)
2. that disk twists and expands into the viewer, and zooms unitll a new menu pops up.

i am just wondering if you or anyone really wanted to start an interface with animations?

DICE

this looks awesome

Lookin' good!

I've been doing a lot of VB.NET projects over the last year and a half or so -- while there are a few drawbacks vs. VB6, the enormous benefits definitely outweigh the drawbacks. Everything works smoother and easier, and the UI improvements within the VS.NET IDE itself (e.g. much better, dynamic Intellisense) are quite useful.

I had actually started work on an app for music, nav, etc., but maybe I'll wait until you post up some of your files to resume work on the UI sections. The weather data seems interesting.

What are you using for music playback? (I'm using WMP9 in my app) And for the UI, are you using DX?

Hey everyone, I'd first like to anwser a few questions:

I was going to use windows registry and .Net built in functions to save my applications working state (i.e. is it playing a song, or was the gps software running. They way we normally do things to remember settings) I've found it SO much easier to tie everything into the database that my media files are going to be stored in..

In fact every media file is just going to be a class that has intrensic controls within itself. (i.e. it plays it self, knows its own working state) In the database, the working media file will have a field called "playing" and "position" only one song in the audio table of the database will have playing=true So when the ignition is cut from the carputer and power is lost to the system.. It will easily be able to recall what it was doing.

When the software starts, it goes to the GUI table in the database (code posted above) It checks the database to figure out what was opened. Then an event handler goes ahead and opens each feature in my software.

Each feature, then calls its own table of settings in the database (via SQL) and remembers what it was doing before the ignition was cut.

Whats your thoughts about doing this through database ?? I really think it streamlines the coding a hell of a lot better.

Now here's some goodies:

Yall need MSIntet control. (ya, ya, you could use winsock.. but wait till you see how easy it is to use Inet)

Q. What is Inet ?
A. It's a control that is similiar to winsock (used to communicate to other computers through a PC's Virtual ports.) Inet can recieve HTTP, FTP even through a proxy connection. For you programmers, think of it has a friendly way to do the same basic stuff winsock can (with limited features)


ok, open a .net new windows project. in the toolbar right click on (Components) and search for (COM components) (yes, inet was designed for VB6) Once, Inet shows up in the components toolbar add it to Form1. Add this code to a button:

change image_and_directory to "C:\img.jpg"
change URL = "http://image.weather.com/images/maps/current/cur_cen_720x486.jpg"

Code:

        Dim bytedata() As Byte

        Dim fs As New FileStream(image_and_directory, FileMode.Create)
        Dim w As New BinaryWriter(fs)

        '*
        'Ok, we've declared the filestreams and opened the binarywriter. 
        'Lets get some work done now
        '*


        '*
        'Tell Inet to get my file (which should be in the URL)
        '*


        bytedata = Inet.OpenURL(URL, 1)


        w.Write(bytedata)

        '*
        'Yup, write my data and close streams!
        '*


        w.Close()
        fs.Close()

I should mention at this point the URL is 1 of 81 maps created my weather.com (I have a list of ALL the static urls that are update by weather.com by the minute) I will also post more code.. so we can all writ our own weather map retreiving software !!

good stuf but im a vb6'er. i'm interested in the static map list tho! i'll figure out the weather thing later, still got more stuff to do on my software first!

I posed the static map list in developer resources as a data base file.

DB of Static Maps

Object persistence via a database is nothing new and sounds like a reasonable design decision. I'm not sure your class design is the most efficient. I prefer to keep my classes as close to reality as possible. In the real world, a song doesn't play itself. That's a method of a mediaplayer. Let your player class maintain which song is currently playing. You can persist that in your database and save a the space you would otherwise waste in keeping this value stored with each song -- as you said, only one of them will ever be marked true anyhow.

Keep up the good discussion.

Thanks, I've actually done it the way you had described I'm just going to test to see how an intrensic audio class (that plays it self) is gunna work.. I'm just curious to see if this will be beneficial or not, beleive me I can already see a ton of problems but I'm just playin with stuff.

To be honest I was thikning of making an audio base class then derrive inhertied classes under that. The base class would almost just do the basic play pause stop.. Everything else would be derrived off of that.

Any thoughts ??
